<p>
The PersistStream interface is the interface to use for all new
components that are able to load and save themselves to a stream.
It should be associated with any <span class="type">BonoboEmbeddable</span> for use by the
container in creating a compound document.
</p>
<p>
This interface works by connecting callbacks to the methods, in
a somewhat deprecated fashion, it is probably better nowadays to
simply sub-class the BonoboXObject and override the epv methods.
Either way, after all the caveats here is an example use:
